Mary Queen of Scots explores the turbulent life of Mary Stuart (Saoirse Ronan). Queen of France at 16 and widowed at 18, Mary defies pressure to remarry. Instead, she returns to her native Scotland to reclaim her rightful throne alongside her cousin Elizabeth I (Margot Robbie) who rules as England’s Queen. Rivals in power and in love, and female monarchs in a masculine world, the two must decide how to play the game of marriage versus independence. Determined to rule as much more than a figurehead, Mary asserts her claim to the English throne, threatening Elizabeth’s sovereignty. Betrayal, rebellion, and conspiracies within each court imperil both thrones—and change the course of history.
